Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Guam for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Guam only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Guam (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider’s entire public billing footprint is essentially single‑payer: total Medicare revenue is $575.9K and there is no Medicaid billing on file, so analyses of payer mix should treat Medicare as the operative population for contracting and utilization review. The absence of Medicaid claims means there is no in‑state Medicaid volume to benchmark against.

Revenue is highly concentrated: the precomputed top‑3 Medicare codes by revenue account for 67.8% of this provider's total Medicare revenue. Those top three codes are 78452 (378 claims, $376 avg paid/claim, $142.1K revenue; 24.7% of total Medicare revenue), A9500 (742 claims, $186 avg paid/claim, $138K revenue; 24.0% of total Medicare revenue), and 99214 (1.2K claims, $94 avg paid/claim, $109.8K revenue; 19.1% of total Medicare revenue).

The code mix points to a practice built around diagnostic and procedural cardiology services with a strong nuclear cardiology component: 78452 (SPECT myocardial perfusion studies) and A9500 (technetium tc‑99m sestamibi) together drive roughly half of revenue, while J2785 (regadenoson; 1.1K claims, $42 avg, $44.5K revenue) and high volumes of stress testing codes (e.g., 93017, 93016, 93018) support a workflow centered on stress imaging and pharmacologic stress protocols. Substantial use of 93306 (transthoracic echo; 1.3K claims, $49 avg, $61.5K revenue) indicates routine ultrasound imaging is also a core service line.

Competitive standing on key procedure codes is markedly above typical national peers: 78452 ranks #226 of 14946 providers nationally (98th percentile; extreme outlier) and A9500 ranks #55 of 4099 providers nationally (99th percentile; extreme outlier), indicating unusually high national volume for nuclear cardiology. 99214 likewise ranks #7674 of 479517 providers nationally (98th percentile; extreme outlier), showing the provider has very high office E/M volume relative to peers. These percentile labels identify the provider as a major national outlier on multiple revenue‑driving codes rather than a modest participant.

Beyond the top three, several diagnostic and monitoring codes are also extreme outliers or notably elevated: 93306 (99th percentile; extreme outlier), 93018 (100th percentile; extreme outlier), and 93227 (100th percentile; extreme outlier) all show volumes far above typical national peers. This pattern—high volumes across imaging, stress testing, and ambulatory ECG interpretation—suggests a high‑throughput diagnostic cardiology practice with repeatable testing workflows.

The mix of high‑volume E/M (99214: 1.2K claims, $109.8K revenue) alongside procedure-heavy revenue indicates the provider combines longitudinal outpatient management with point‑of‑care diagnostic services; the presence of both frequent office visits and large imaging/pharmaceutical supply billing implies bundled operational capabilities (clinic plus onsite imaging/radionuclide administration). This combination can affect payer negotiations and utilization management strategies because both encounter-based and supply/procedure reimbursement streams matter.

Tenure is long: NPI enumeration date is 2008-09-16 (~18 years ago), indicating an established billing history and likely continuity of practice patterns over time. That duration supports interpreting the outlier volumes as sustained operational characteristics rather than a short‑term spike.

Concentration risk and contracting implications: with $575.9K total Medicare revenue and 67.8% of that coming from three codes, the provider’s financial profile is sensitive to reimbursement or utilization changes for nuclear cardiology and high‑level E/M. Payers and network managers should prioritize review of utilization policies, prior‑authorization pathways for SPECT/pharmaceuticals, and site‑of‑service coding to understand exposure and to structure any performance or utilization monitoring appropriately.
